| |
When asynchronous compaction was introduced, the /proc/sys/vm/compact_memory handler should have been updated to always use synchronous compaction. This did not happen so this patch addresses it. The assumption is if a user writes to /proc/sys/vm/compact_memory, they are willing for that process to stall.
